Summary

This started life as a customisation of Jon's excellent Simple Tool Changer https://properprinting.pro/product/creality-ender3s1-simpletoolchanger/ but morphed into a tool changer besed on an x-axis linear rail.

Basically, once the MGN12H linear rail is mounted
(1) Bolt the Carriage Plate to the MGN12H carriage (four M3 bolts)
(2) Bolt the Slider to this Carriage Plate (2x M3 bolts)
(3) Bolt the Sprite Plate to the rerar of the Sprite extruder (3x M3 bolts)

And that's it. Slide the extruder onto the mounting plates, wait for the click of the snap lock, and start printing.

NB
This is a work in progress because I have not catalogued the hardware (ie M3 bolts) yet.

Also - please note that on AliExpress, there are a number of different versions of the supposedly "standard" MGN12H rail/carriage. Ensure you order a carriage which has the standard 20mm x 20mm square mounting holes. Many of them have 20mm x 15mm spacing. These are the ones I used. https://www.aliexpress.com/item/32806622073.html?spm=a2g0o.order_list.order_list_main.11.2d661802AzBGte

Finally, I've included a screenshot of the correct print orientation. Note that the supports are minor, and very easy to remove.

And add a little lubricant to the sliders to facilitate easier movement.

I have included the entire STEP file so that you can adjust/change or otherwise customise the design.
